This paper introduces the Spectral Clustering Equivalence (SCE) algorithm which is intended to be an alternative to spectral clustering (SC) with the objective to improve both speed and quality of segmentation. Instead of solving for the spectral decomposition of a similarity matrix as in SC, SCE converts the similarity matrix to a columncentered dissimilarity matrix and searches for a pair of ...

We introduce new CP models for the many-to-many stable matching problem. We use the notion of rotation to give a novel encoding that is linear in the input size of the problem. We give extra filtering rules to maintain arc consistency in quadratic time. Our experimental study on hard instances of sex-equal and balanced stable matching shows the efficiency of one of our propositions as compared ...

We propose a stable and efficient particle-based method for simulating highly viscous fluids that can generate coiling and buckling phenomena and handle variable viscosity. In contrast to previous methods that use explicit integration, our method uses an implicit formulation to improve the robustness of viscosity integration, therefore enabling use of larger time steps and higher viscosities. W...

Laid down in this paper are the foundations on which the design of engineering systems, in the presence of an uncontrollable changing environment, can be based. The changes in environment conditions are accounted for by means of robustness. To this end, a theoretical framework as well as a general methodology for model-based robust design are proposed. Within this framework, all quantities invo...

PURPOSE To introduce the concept of dose-mass-based inverse optimization for radiotherapy applications. MATERIALS AND METHODS Mathematical derivation of the dose-mass-based formalism is presented. This mathematical representation is compared to the most commonly used dose-volume-based formulation used in inverse optimization. A simple example on digitally created phantom is presented. The pha...

a total of 1440 arian chicks were used in this study to determine the effects of diet formulation methods on performance and blood parameters of arian chicks. eight diets were arranged in a 2×2×2 factorial design with 2 methods of energy expression (apparent (amen) and true (tmen) metabolizable energy corrected to n equilibrium), 2 methods of amino acids content of feeds (total (taaf) and diges...

The paper presents the Constructive Dialogue Model as a new approach to formulate system goals in intelligent dialogue systems. The departure point is in general communicative principles which constrain cooperative and coherent communication. Dialogue participants are engaged in a cooperative task whereby a model of the joint purpose is constructed. Contributions are planned as reactions to the...

Recent research showed the benefits of adopting formal ontologies as a means for accessing heterogeneous data sources. The use of an ontology not only provides a uniform and flexible approach for integrating and describing these sources, but it can be used to improve the usability of an integrated system by guiding the final user to formulate his/her information needs. More precisely, the task ...

The purpose of this study was to develop and optimize an isotretinoin oil-based capsule with specific dissolution pattern. A three-factor-constrained mixture design was used to prepare the systemic model formulations. The independent factors were the components of oil-based capsule including beeswax (X₁), hydrogenated coconut oil (X₂), and soybean oil (X₃). The drug release percentages at 10, 3...

an oral sustained-release floating tablet formulation of metformin hcl was designed and developed. effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and hpmc-peo polymer combination, respectively. tablet composition was optimized by response surface methodology (rsm). seventeen (17) trial formulations were analyzed according to box-behnken desi...
